Number What with a Bullet?
During that year FBI statistics counted
500 murders in Chicago,
386 in Detroit,
193 in New Orleans, and
88in Washington, D.C. The combined total of homicides in those four cities was 1,167 for that year, or approximately 7.8 percent of all murders that occurred in the United States in 2012.
Even if the sum total of all intentional homicides for 2012 occurring in those four cities were ignored, it wouldn't change the rankings previously described very much: The United States would drop a few notches down from its already fairly low position on the global homicide rate chart (but still not close to "fourth from the bottom"), and the U.S. would drop from 8th to 11th in a list ordered by the absolute number of intentional homicides (still very far away from "fourth from the bottom").
